Diagnosing Common Central Heating Problems
The last thing you want is to have your home heating stop functioning when it is cold outside. If you have a central heating system, there are certain problems that are common and that you should know about. You may not necessarily be able to repair them yourself, but at least you will be able to diagnose the problem so you can tell the heating services technician what you think it is when you call for repairs. Here are the most common central heating problems.
No Heat at All
If you are getting no heat at all, you need to do some checking around to figure out what the problem may be. The simplest solution is that the thermostat is not turned on. In this case, all you have to do is adjust the temperature setting so it is high enough to make the furnace kick in. Another problem could be that the unit is not getting electricity. If this is the case, you will need to hire an electrician.
If you are getting some heat but not as much as you should be getting, there are several things that could be causing the problem. If there are radiators in the home, they may have air trapped inside and will need to be bled. Another possible cause is a leak or a blockage in the ductwork. For both problems, you will need to contact a heating services company like Guy Hyde Gasfitting & Appliance Service.
If the temperatures in your home are fluctuating from very hot to very cold, the problem is likely originating with the thermostat. You will need to contact a heating services technician to have the thermostat calibrated again. In the event that the thermostat can't be calibrated, it will need to be replaced. Opt for a programmable thermostat, because it will only come on when you want it to and you can save money on your energy bills.
Pilot Light Issues
If you are not getting any heat, it could be that the pilot light is out, which is often just a matter of relighting it. If it won't ignite, it could be a problem with the gas supply and you will need to contact your gas supplier for repairs. Even if it does ignite, check to make sure that it is at the proper strength. If the flame is not small and yellow instead of large and blue, it could mean that the pilot light is weak, which can be hazardous because it can cause carbon monoxide levels in the home to elevate.
